I think the gyros are just for failsafe level flght.


I meant Gyros for the RPG7 launcher sights. The idea is that the
person firing the RPG7 turns a dial to close in a recticle around the
helicopter. This estimates the range and gives the amount of
elevation needed. At the same time by tracking the helicopters for a
few seconds the 'rate' of the helicopters crossing speed is calculated
and in this way a complete 'firing solution' is available. The Gyros
are needed to provide a measurement basis if a tripod can't be
provided. The RPG7 is then launched against the helicopter. The
lighter RPG7 rounds have a fair degree of velocity and therefore
range. If a special anti-aircraft fragmentation round is supplied
with a simple (laser) proximity fuse I think a very effective weapon
would be produced. I immagine such a round would have a lethal
distance of quite a few meters and a near miss would be enough.

In the absence of such a computing sight a WW2 style griticule could
be provided with the opperator estimating range and speed.

The range would be restricted to about 1000 meters but I salvo of half
a dozen such rounds might be very effective.

I suspect that someone must have tried to create a guided RPG7 round.
It wouldn't take much to put laser beam riding in.

Previosly, a thread went into the merits of flying low. Maybe
that
works for SA-7s, but flying low puts the choppers in the range
of the
RPGs.

The news never states the type of RPG, but if it is the RPG-7,
the
range is 300 meters.

Part of the new plan was to fly at night, but given the
description of
the witnesses, it seems like this flight was during the day.

Interesting aticle.

If the RPG7 launcher was fitted with a WW2 style lead computing
sight
and given a radar/laser proximity fused fragmentation round it
might
be quite effective at ambushing helicopters.

Single chip gyroscopes are now available for radio contolled model
aircraft. In the absence of gyroscopes for obtaining rate
information
a tripod could be provided as a basis. Radar/laser promximity
fuses
are also not difficult or expensive items in this day and age.
